The clinical studies that supported the approval of the one available CBD drug product identified risks related to the use of CBD, including liver toxicity (damage), extreme sleepiness, and harmful interactions with other drugs.
We especially want to learn more about the effects of CBD during pregnancy and while breastfeeding, including, for example, whether and to what extent the presence of CBD in human milk harms the breastfed baby or the mother’s milk production.
Moreover, CBD has known risks for people in general. Based on clinical studies in humans, risks can include the following:
What about hemp seeds?
There is no comprehensive research studying the effects of CBD on the developing fetus, pregnant mother, or breastfed baby. FDA is continuing to collect and study the data on the possible harmful effects of CBD during pregnancy and while breastfeeding. However, based on what we do know, there is significant cause for concern.
We also know that there is a potential for CBD products to be contaminated with substances that may pose a risk to the fetus or breastfed baby, including THC. We have also heard reports of CBD potentially containing other contaminants (e.g., pesticides, heavy metals, bacteria, and fungus); we are investigating this.
FDA is studying the effects of CBD use from different angles, such as: (1) the use of CBD-containing products, like food, cosmetics, or supplements, over a person’s entire life; and (2) the effects of using these various products in combination. There are many unanswered questions about the science, safety, and quality of products containing CBD.
If you are considering using cannabis, or any products containing THC or CBD, you should be aware of the following:

Geary adds, “Every mother’s metabolism is different; the absorption into the blood stream is different, and the actual dosage of the CBD listed is not considered accurate or reliable.” She also brings up a point about the lack of regulation surrounding CBD products. This March, the FDA issued a statement promising to advance regulatory practices of CBD, admitting wide gaps in data and a lack of market transparency. The same report notes, “we are not at a point where we can conclude that unapproved CBD products are safe for use” in lactating women. Thomas adds that for reliable data, we’ll need to evaluate a couple thousand people over at least 15 years. Current data doesn’t meet either of those criteria.
What the Data Says About CBD and Breastfeeding
Try to use nursing sessions as a time to pause and reset, letting the oxytocin that’s released during breastfeeding help you enter a state of calm. Play soothing music or a guided meditation, practice deep breathing, and remember that this stage of life is temporary.
Thomas adds that although CBD can seem like a “pathway to self-care,” it’s only one of many wellness tools. She urges women to get to the “root of the stress or anxiety on the road to recovery.” Asking for help is critical. “When we think of stress and how to mitigate it because life is too much, that becomes a pathway for pain and trauma to embed,” she says. But it’s also an opportunity to do the work necessary to heal. “Reaching for a cure-all,” she says, “helps us turn away from a life we’ve created when we need to be so committed to it right now.”
Geary (who notes that as a pediatrician with a license to provide medical marijuana —CBD and THC products—she’s not an anti-marijuana doctor), says using CBD when breastfeeding just isn’t a safe gamble. “During the time of the developing fetus, through until age three years of life, the infant’s brain reaches 80% of its full adult volume. Any unnecessary exposure, especially in those vulnerable first three years, is worth considering very seriously.”
